This usually happens when you have used the wrong amtlib file version.
There are 3 different amtlib files for Mac and 7 different amtlib files for Windows. Make sure you have downloaded the right file.
If you have downloaded the wrong file accidentally or you are not sure if you downloaded the right file, please email [email protected] us know or send a private message on our Facebook page. Please include the email address you used to download. All messages are answered once a day.
For Mac users only:
If you are sure you have downloaded and used the right file, then make sure you are replacing the whole amtlib.framework file, not just the amtlib file inside it!
